If you hear a phrase like “six and a half minutes of terror,” you generally don’t expect it to be about something that will end well. This is an exception, hopefully.

In this case the phrase is being used to describe the landing of NASA’s InSight Spacecraft on the surface of Mars. It will happen this Monday (Nov. 26th), and it’s definitely the most nail-biting part of the mission.

That’s because landing on Mars isn’t just hard — it’s very hard! Here’s a great two minute explanation of why that’s the case.

That’s the big picture. Now here’s Rob Manning, Chief Engineer at JPL, explaining the specifics of what the nail-biting will be about this time.

Here’s a glossier visualization from NASA’s partner on the mission, Lockheed Martin.

Lockheed Martin also posted this neat 360° video that shows the actual InSight spacecraft coming out of it’s shipping container in their clean room in Littleton, CO.

Assuming InSight makes it to the surface of Mars safely, it has a number of unique science objectives to carry out.

The name InSight is actually short for “Interior exploration using Seismic investigations, geodesy and heat transport,” and its name pretty much explains what it’s going to do. Here’s a video about the multiple science objectives of the mission.

NASA will be broadcasting their six and a half minutes of terror on NASA Live. Commentary will run from 2:00 p.m. to 3:30 p.m., and the actual landing should be between 2:30 p.m. and 3:00 p.m. (EST).
